Application filed April 9, 1915; Serial No. 20,265.

To all whom it may concern:

Be it known that I, CHARLES H. DE FREHN, a citizen of the United States, residing at J ohnstown, in the county of Cambria and State of Pennsylvania, have invented a new and useful Chair, of which the following is a specification.

The device forming the-subject matter of this application is a retaining member, adapted to form a connection between the seat of a high chair and the movable tray thereof, to the end that the occupant of the chair may not slide out of the chair between the tray and the seat, and also to prevent a rising of the tray. 7

The invention aims to provide novel means for assembling the retaining member with the seat and with the tray and to provide means whereby at the will of an operator, the retaining member may be tightened up.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

W'ith the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings :Figure 1 shows in front elevation, a high chair wherewith the device forming the subject matter of this application has been assembled; Fig. 2 is a fragmental vertical section showing a high chair equipped with the device forming the subject matter of this application; Fig. 3 is a fragmental bottom plan of the seat of the chair, looking upwardly; Fig. 4 is a horizontal section taken along the lower face of the seat of the chair, looking downwardly.

In the accompanying drawings there is shown a high chair 1 comprising a back 2, a seat 3, arms 4, a tray 5 adapted to rest on the arms 4 and comprising. extensions 6 pivoted to the back 2 as shown at 7-all as well known and clearly understood by those skilled in the art.

midway between the arms 4 is a securing element 8 which may be in the form of a headed pin. I

The invention comprises a retaining member 10 which may be a flexible strap, the upper end of the retaining member 10 being looped as at 11 to the lower end of a link 9, the loop being maintained by means of a rivet 12 or in any other suitable manner. The upper end of the link 9 is contracted. The link 9 may be slipped over the pin 8 detachably, so as to connect the upper end of the flexible tray 5. r

The invention comprises a horizontally swinging lever 14 embodying a handle 15 and a laterally enlarged head 16. A fulcrum element which may be a flat headed screw 17 passes upwardly through the head 16 of the lever 14 and attaches the lever to the lower face of the seat 3. As shown at 18, one edge of the head 16 is extended, so as to give an increased bearing area between the upper face of the head 16 of the lever 14 and the lower face of the seat 3.

The flexible retaining member 10 is extended downwardly across the forward edge 19 of the seat 3 and is carried rearwardly beneath the seat, the inner or lower end of the flexible retaining member being united by means of a securing element 20, which may be a round headed screw, with the head 16 of the lever 14 adjacent the end which is opposite to the handle 15. Inserted into the lower face of the seat 3 is a stop 21 for the handle 15 of the lever 14, the stop if desired being in the form of a depending pin.

In practical operation, the link 9 is, assembled with the securing element 8, and thus the upper end of the flexible retaining member 10 is united with the forward edge of the tray 5. The lever 14 then is swung around on its fulcrum 17 toward the forward edge 19 of the seat 3, until the handle 15 of the lever abuts against the stop pin 21. By this operation, the flexible retaining member 10 is tightened up. lVhen the retaining member 10 is disposed as above described, the occupant of the chair, straddling the retaining member 10, obviously cannot slide out of the chair between the tray 5 and the seat 3.

Noting Fig. 3 of the drawings it will be observed that when the handle 15 of the lever 14 is in abutment with the stop pin 21, the securing element 20 which unites the reretaining member 10 with the taining member with the head 16 of the lever has passed to one side of the fulcrum V 17 of the lever. Therefore, when a strain is brought upon the retaining member 10, the,

retaining member tends to swing the lever 14 in the direction of the arrow A in Fig. 3 and to maintain an abutment between the handle 15 of the lever and the stop pin 21, a loosening of the retaining member thus being impossible.

For convenience in claiming the invention, the lever 14 may be alluded to as a tightening device, the seat 3 and the tray 5 being mentioned as cooperating elements, one of which, to Wit the seat 3, is provided with the tightening device above alluded to.

Having thus described the invention, what is claimed is 1. A high chair embodying as cooperating elements, a seat and a movable tray; a tightening device on one of said cooperating elements; and a flexible element assembled with the tightening device and with the Copies of this patent may be obtained for other of said cooperating elements, the flexible element being located adjacent the forward edges of the seat and the tray and being located intermediate the sides of the chair.

2. A high chair embodying a seat and a movable tray; a lever fulcrumed on the seat; a retaining member connected at one end with the lever; and means for detachably connecting the other end of the retaining member with the tray, the lever being located to the rear of the forward edge of the seat, whereby when the retaining member is detached from the tray, the retaining member may hang in a depending position beneath the seat.

In testimony'that I claim the foregoing as my own, I'have hereto aflixed my signa, ture in the presence of two witnesses.

CHARLES H. DE FREHN.
